Subject: [PATCH] ci(e2e): install a CJK font on the e2e runners

The runners have no font covering Hangul, Han or Kana, so any spec that
asserts how CJK text renders is measuring tofu rather than the glyph.

That is not hypothetical. An end-of-row preedit spec added for #12729
measured the composition overlay at 1.02 cells against an 8.43px grid
and failed its "wider than one cell" assertion. The overlay is
shrink-to-fit with no width of its own, so it tracks the glyph's advance
rather than the two cells the grid reserves for a wide character. With
no Korean font that advance is one cell, and the assertion cannot
distinguish a real result from a missing font - which is exactly the
question that spec exists to answer.

fonts-noto-cjk covers all three scripts and is added to both jobs that
execute specs, the sharded suite and the changed-spec job, plus the ssh
docker lane so the three stay consistent.

This does not make any spec pass on its own. It makes the CJK ones
mean something.
